Cobalt Drier is a concentrated metal carboxylate in mineral spirits, containing 6% cobalt, and is an active, primary surface drier.
Cobalt is a primary oxidizing drier. Used alone and in thick applications of paint it has a tendency to cause wrinkling. Cobalt is generally used in combination with lead, zirconium, calcium or combination of these metals as a drying initiator.
Typically, 0.01% to 0.2% of cobalt metal is added to oil and alkyd paint based on the weight of the binder.
Directions
Add one drop per 10 ml (about 2 teaspoons) of paint. Suggested use levels should be verified with tests.
